“…As a whole, it is shown in Figure 5, the MOE values obtained follow the JAS 234:2003 standard with a minimum value of 75.000 kg/cm 2 . The value of MOE of laminated boards in this study was higher when compared to the zephyr-shaped laminated bamboo study of 80.000 kg/cm 2 [30] and in betung bamboo laminated boards of 10.001.77 kg/cm 2 [24]. From the results obtained, the MOE value of untreated bamboo was higher than treated bamboo.…”

“…Wahyudi [23] reported differences in density caused by differences in the number of layers of lamina. In addition, the density of bamboo varies based on the bamboo section and the conditions of the growing location [24]. Based on the results of the density analysis of variance, it was shown that immersion time had a significant effect on density.…”

A laminate board is a composite board formed from a combination of several laminates and glued together using adhesives in the parallel direction of the fibers. Belangke bamboo, as a substitute for wood, can be used as raw material for making laminated boards. Belangke bamboo has fairly good strength but has a weakness, namely, being vulnerable to attacks by destructive agents. Adding boric acid immersion treatment is one of the modifications to laminated boards to increase their strength and durability against attacks by destructive organisms. This study aims to analyze the physical and mechanical properties of laminated boards from striped bamboo with the effect of immersion treatment from 0 hours, 6 hours, 12 hours and 24 hours. The laminated board consists of 3 layers measuring 30 cm long, 15 cm wide, and 0.5 cm thick, which are glued using 280 g/m2 isocyanate adhesive and cold pressed for 24 hours with conditioning for ten days. The results of the physical properties test of this study obtained the average value in the weight percent gain (WPG) test ranged from 2.66-3.33%, density ranged from 0.79-0.97 g/cm3, moisture content ranged from 12.67%-13.40%, and delamination ranged from 2.37-7.77%. The results of mechanical properties testing showed the average value of modulus of elasticity (MOE) testing of 112383.20-127377.74 kg/cm2, modulus of rupture (MOR) of 371.69-578.95 kg/cm2, and shear strength ranged from 14.61–27.73 kg/cm2. From the analysis of variance, the best-laminated board is found in the 6-hour boric acid immersion time.

Teknologi laminasi merupakan salah satu alternatif untuk mengkombinasikan antara bahan kayu dan non kayu menjadi produk papan. Bahan baku papan laminasi yang digunakan adalah kayu rajumas dan bambu petung. Kayu rajumas (Duabanga mollucana) memiliki kelas kuat IV-V. Bambu yang digunakan dalam pembuatan papan lamianasi harus memiliki syarat yaitu dimensi panjang, lebar, dan tebal yang dapat dikonversikan dalam bentuk papan atau balok. Penelitian ini bertujuan untuk mengetahui kekuatan fisika dan mekanika papan laminasi kombinasi dari kayu rajumas dan bambu petung serta pengaruh berat labur, tekanan kempa dan interaksinya terhadap kekuatan sifat fisika dan mekanika papan laminasi. Metode penelitian yang digunakan menggunakan metode eksperimen dengan rancanga percobaan faktorial dengan 2 faktor dan 4 perlakuan dengan 3 kali ulangan. Berdasarkan hasil penelitian yang telah dilakukan maka berat labur, tekanan kempa dan interaksinya tidak berpengaruh nyata terhadap pengujian sifat fisika tetapi berpengaruh nyata pada pengujian sifat mekanika papan laminasi. Hal ini ditunjukkan dengan adanya perbedaan yang signifikan antara perlakuan B1T1 dengan perlakuan B2T1 pada uji MoE dengan nilai signifikan 0,036 dan 0,033 serta pada uji MoR dengan nilai signifikan 0,001, 0,007, dan 0,035. Berdasarkan nilai sifat fisika dan mekanika maka papan laminasi kombinasi kayu rajumas dan bambu petung masuk dalam kelas III yang dapat digunakan untuk keperluan konstruksi berat terlindung. Combination of Rajumas Wood and Petung Bamboo as a Laminated Board Product Abstract Lamination technology is an alternative to combine wood and non-wood materials into board products. The raw materials used for laminated boards are rajumas wood and petung bamboo. Rajumas wood (Duabanga mollucana) has a strength class IV-V. Bamboo used in the manufacture of lamianation boards must have requirements, namely length, width, and thickness dimensions that can be converted in the form of boards or blocks. This study aims to determine the physical strength and mechanics of laminated boards combined from rajumas wood and petung bamboo as well as the effect of labur weight, felt pressure and their interaction on the strength of physical properties and mechanics of laminated boards. The research method used used experimental method with factorial experimental design with 2 factors and 4 treatments with 3 replications. Based on the results of the research that has been done, the overburden weight, compression pressure and their interactions do not have a significant effect on testing the physical properties but have a significant effect on testing the mechanical properties of laminated boards. This is indicated by the significant difference between the B1T1 treatment and the B2T1 treatment in the MoE test with significant values of 0.036 and 0.033 and in the MoR test with significant values of 0.001, 0.007, and 0.035, respectively. Based on the value of physical and mechanical properties, the laminated board of a combination of rajumas wood and petung bamboo is included in class III which can be used for heavy protected construction purposes.
